TO ALL WHOMIT MAY CONCERN:

Be it known that I, FRANK HATCH, of La Crosse, in the county of LaCrosse, and State of Wisconsin, have invented a new and useful ImprovedAdjustable Window-Screen; andI do hereby declare and make known that thefollowing is a full, clear, and exact description ofthe same, referencebeing had to the accompanying drawi'ngs, and the letters and iguresmarked thereon, which form part of this specification.

My said invention consists in constructing the frame of a window-screenin two sections or parts, sliding laterally by each other, and connectedby a. rubber, or other elastic cord or spring, lin scha manner that theaction of the spring or its equivalent holds the outer'edges of theframes firmly in place againstthc window,.

thus adapting the screen to windows of dil'erent widths, as ishereinafter fully described.

To enable thosefskilled'in the art to understand how to construct anduse my invention, I will proceed to describe the sameI withparticularity, making reference in so doing to thev aforesaid drawings,in which- Figure 1 represents a side elevation of my invention, asapplied toa window for use.. Figure 2 is an end viewl of the same,Figure 3 is a plan or top view thereof, and

Figure 4 is a front elevation of my invention, the sections of the framebeing withdrawn from eachother,- i

showing the elastic connection whereby they are held in the properposition in the window.

Similar letters of reference in the several figures denote the sameparts of my invention. A B represent two frames of suitable width andlength, the widthl thereof being equal, and the upper and lower edges ofone of said frames being provided with a metallic strip, a, whose edgesare bent down, as clearly seen in fig. 2, in order to form a guide orway in which the other member of the frame may slide laterally, so thatwhen arranged together, as seen in figs. l, 2, and 3, they may be movedout or drawn in, soras to adapt the screen to windows ofdi'erentwidthsrwhile it will be observed that the metallic strip a formsa straight face, with the section B of the frame lying close againstithe lower member of the window-sash, vwhen the same is raised up to adistance corresponding with the height of the screen, as indicated intig. 1, and the inner end of the screen-` frame B also lies closeagainst the gauze upon the frame A, thus rendering the screen perfectlysecure against any insects or other substances which said screens `areordinarily designed to exclude from the house while the sash is open.Instead of the peculiar ymode herein shown. of forming the ways for thesection B to slide in, any other suitable device may be employed whichwill eii'ect the same purpose.

Upon the inner end ofthe section B is a ring or hook, b, and upon thcinner end olf the frame A is ahook', c, said hook and loop or ring beingconnected by an elastic ring, strap, band, or spring, indicated by zi',which, while yielding to permit the screw tobe shortened at pleasure,operates'to entend the length ofthe screen, and force the ends thereofagainst the casing of' the windows, thus securing it rmly in place, andit is obvious that this screen can be readily placed at the top of thewindow when desired to lower the upper sash, and can also b'e moved upand down to permit the shutters to be opened or closed when desired.

Having described the construction and operation of my invention, Ivwillspecify what I claim, and desire to secure by Letters Patent.

I claim the combination of the twosections or frames A B wit-l1 aspring, d, so arranged that the spring will -operate to force saidsections outward against the window-casing, and retain the screen in anydesired position, substantially as and for the purposesspecified. l-

l FRANK HATCH.
